There are Three Ways Heat, or Thermal Energy, Can Be Transferred

A hotter object passes thermal energy to a colder object by touching it so their particles bump into each other.

A hotter object reaches thermal equilibrium and gives its extra heat particles away to nearby objects.

A hotter object is placed on one side of an insulator and a colder object is placed on the other side of the insulator.

A hotter object has particles that spread through the air as gases and warm the air near the colder object.

The water near the bottom expands and becomes less dense.

The water near the bottom transfers heat and becomes a gas.

The water gains molecules and stays near the bottom.

The water vibrates and is seen as light near the bottom.

that convection only happens with liquids and solids

that humans can use infrared light to gain heat

that hot and cold water create currents as heat transfers

that boiling rice is a good way to show convection in water

It shows how humans are able to see many wavelengths.

It shows that infrared light is outside the range of visible light.

It shows how hot infrared light can get on a sunny day.

It shows that gamma rays and x-rays are types of radiation.
